PATENT *oF 1cE Application filed 0cto be r2 1925. serial No. 5 9,985.

To all whom it may concern:

Be it known that I, MOSES SAAD, a subject of the King of Great Britain, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Molding Machine, of which the following is a specifications 7 It is, an object of this invention to provide a molding machine for production work wherein at least one match plate having a-pattern secured thereon and one platten are so mounted on a constantly moving rotary. machine that" at a predetermined position of the machine the match plate is raised against the underside'of a molding box, the platten is moved downwards-to pack'wsand into the box-and is then raised again after which the match plate is low ered from the molding box so that the latter may be taken away by suitable means while the machine continues to rotate.

Another object of the invention is to pro vide a molding machine having automatic means for permitting sand to flow into the molding 'boxes after the pattern has been raised into position in the box and prior to the lowering of the platten. v

A further ob'ect of the inventionis to provide a molding machine wherein the maximum and minimum heights of the racks on which the match plates and plattens are mounted are subject to adjustment the aid of the accompanying drawings, in

which Fi'gurei1 illustrates a plan view of the molding machine showing also part oflthe conveying mechanism that may be, em

ployedfor carrying the molding boxes.- Figure 2 is a sectional elevation' of the machine and also shows part of the conveying mechanism. j p

Figure 3 is an elevation ofthe machine showing the sand pipe and automatic means for operating the valve inthe pipe.

Figure 4L is a section on the line 4-4. of Figure 2.

Figure 5 gure 2.

is a section on the line 55 of Figure is detail illustrating the 2 method of operating the valve in the sand,

P p Referring to the drawlngs, 1 designates the bed of the machine to which an upright 2 is secured as by the nut 3.. A sleeve 4 rotatably arranged around the lower. part of the upright rests on aball thrust-ring 5.

Fast 0n the sleeve and in proximity tothe thrust rlng'is a gear. 6' which meshes with" the pinion 7' on the shaft 8 which latter is driven by the motor 9. V I

Integral with the sleeve is a disc lO, and 11 indicates radial walls extending out. wardly from the sleeve and upwardly from the disc. The number of theseradial walls depends upon the'number of molding units.

rackv and theother with its platten rack. V

On the upper end of the upright 2-.two' stationary plates '19 and 20 arese'cured as by cotter pins 21 and 22 respectively. In

the plate 19 is,,a,cam slot 23 and the pee 20 has a second cam slot 24:. On theradi'al walls arms I 25 are pivotally mountedthe outer ends of which are adapted to travel round in the cam slot 23, and inte-rmediately on each arm a connecting member 26 is fastened," the other end of which is' con-Q nected to a-segmental gear 17. Av second set of arms 27 are" also pivotally mounted on the radial walls and have outer ends which travel round in the camslot 24:. A

connecting member 28 is fastened intermedr' ately to each armla'nd also to one of the segmental gears 18. 4:5 and 4C6 are reinfOrcQ ing plates placed against radial walls.

At the lower end of each pattern rack 14 a match plate 29 is secured. A pattern 30 is fastened onto each match plate. The size of the patterns is preferably such] that they will occupy mostof the length and Width of the molding box 81 and similarly; the size of eachiplatten 82 mounted onthe lower end of its rack 15 is such as to nicely enter within the sides of the molding boxes.

right thereon, a sleeve around said upright, means for rotating said sleeve, a disc integral with said sleeve, radial walls integral with said sleeve, guides on each of said radial walls, a platten rackv and a pattern rack in each of said guides, and means for moving said racks vertically as said sleeve rotates. I

9. In a molding machine, a'bed, an upright mounted thereon, a sleeve around said upright, means for rotating said sleeve, a disc integral with said sleeve, radial walls integral with said sleeve and disc, guides on said radial walls, a pattern rack in a guide on each radial wall, a platten rack in a guide on each radial wall, two stationary plates one above the other at the upper end of the upright each having a cam slot therein, and two arms mounted pivotally on each radial wall, one of which extends into each cam slot.

10. In a molding machine, a bed, an upright thereon, a sleeve around said upright,

means for rotating said sleeve, a disc integral with said sleeve, radial walls integral with said sleeve and disc, guides on said radial walls, a pattern rack in a guide on each radial wall, a platten rack in a guide on each radial wall, a segmental gear coacting with each of said racks and pivotally mounted on one of the radial walls, stationary plates secured towards the upper end of said upright, arms pivotally mounted on! said radial Walls and extending into cam slots in said stationary plates, and a connecting member from each of said arms to one of said segmental gears. v

11. In a molding machine, a bed, an up right thereon, a sleeve around said upright, means for rotating said sleeve, a disc integral with said sleeve, radial walls'integral with said sleeve and said disc, stationary plates secured one above the other on said upright each having a cam slot therein, a guide on each of said radialwalls, a pattern rack and a platten rack in each of said guides, teeth in sa1d racks, a segmental gear meshing with each of said racks, all the segmental gears coacting with the pattern racks being actuated vby arms terminating in one of the camslots, all the segmental gears cooperating with the platten racks being actuated by arms terminating in the other cam slot, a platten at the lower end of the platten rack, anda match plate at the lower end of the pattern rack.

12. In a molding machine, a bed, an upright mounted thereon,'a sleeve around said upright, means for rotating said sleeve, guides on said sleeve, pattern racks in said guides, and platten racks in said guides, in combination with lugs on said guides adapted to open a valve in a sand pipe as said guides rotate.
